A 42 55 mL solution of weak acid is titrated with 0 471 M NaOH It requires 24 47 mL of the NaOH titrant to reach the equivalence point Based on the titration curve it is determined that Ka 7 6 x 10 8 for the weak acid Based on this information what was the pH after 30 93 mL of NaOH was added Write your answer to 2 decimal places ie 1 23 or 12 34 Answer At a certain temperature silver bromide AgBr has a value of Ksp 6 5 x 10 13 At this temperature what is the molar solubility of AgBr in the presence of 0 0044 M HBr Report your answer to two significant figures i e 1 2E 10 M
